ABSTRACT:
A filter flushing arrangement is provided and includes a first filtering device, a second filtering device, and a valve arrangement connected to the first and second filtering devices. The valve arrangement is operative to change the direction of fluid flow through the first filtering device upon a filter element therein becoming clogged to flush the particles to the second filtering device which collects the particles on a filtering element therein and subsequently allows the foreign particles to freely settle to a collection basin. Some form of vibration and/or a burst of fluid from a fluid accumulating mechanism may be used to free the particles therefrom and allow them to settle to the collection basin. The collection basin is capable of collecting the particles over a long period of operation of the fluid system.
